1x3 Raman Filter WDM for DTS Systems(1450/1550/1650nm)

The Raman Wavelength Division Multiplexer Module is a low loss and High reliable and stable components which compliant with G.695 standard and widely used in Raman DTS systems.

  • Singlemode or Multimode

    (9/125um, 50/125um, 62.5/125um)

    Customized Connector

    (FC, SC, LC ... with APC or UPC)

Specification

  • This 1x3 Raman WDM is based on TFF (thin film filter) technology and can transmit multi wavelengths on one optical fiber to increase the network capacity, it used to separate and combine different signal wavelengths at 1450nm, 1550nm, and 1660nm (or 1650nm). Raman Filter WDM Designed by GEZHI Photonics Co.,Ltd with low insertion loss and high isolation Characteristic. It's widely used in Raman DTS systems or other fiber test or measurement systems.
